How Horner analysis is used
After a stabilized production period, the well is shut in and pressure recovery is plotted against Horner time ratio. A clean middle-time-region trend supports estimates of effective permeability, extrapolated reservoir pressure, and near-wellbore skin.

Early-time wellbore storage and late-time boundaries can invalidate a straight-line selection. Screening results should be reviewed by a qualified well-test engineer before operational or reserves decisions.
